Fortuynia shibai adults also show porous areas on all femora and trochanters III and IV.

4F7B1E5DFFABFFE8FF272CEFFC7EB683.taxon	discussion	Remarks Fortuynia churaumi adults show a specific reticulate pattern (fine dense granulation interrupted by non-granular lines) on their femora (see Pfingstl et al. 2019 b, Figure 3), this pattern is already observable in the tritonymph. Fortuynia shibai and F. churaumi may occur syntopically in some locations on the Japanese islands (Pfingstl et al. 2019 b). Adults can be easily distinguished and the same applies to juveniles allowing to easily separate them if contained in a single sample. Fortuynia shibai immatures always show distally barbed notogastral setae (vs. smooth in F. churaumi) and these setae are considerably longer than in F. churaumi.	en	Pfingstl, Tobias, Hiruta, Shimpei F., Hagino, Wataru, Shimano, Satoshi (2021): Juvenile morphology of seven intertidal mite species (Acari, Oribatida, Ameronothroidea) from the East Asian region.

4F7B1E5DFFA8FFE6FC2B2D92FA32B82C.taxon	discussion	Remarks When Marshall and Pugh (2002) described Fortuynia rotunda from African coasts, they gave short information on the legs, e. g. colour and length of segments, and only details about the setae of genu I and II (p. 179, Figure 4 (b )). Karasawa and Aoki (2005) provided a redescription of F. rotunda based on their specimens found on the Japanese Ryukyu islands but also gave very few information about the legs, e. g. lengths of segments, smoothness of claws. Accordingly, we present herein the setation and solenidia for the legs of this species for the first time in detail and although these formulas may be the same for all Japanese F. rotunda, they may differ in the African F. rotunda. Therefore, the development of leg setation given in the present paper is so far only valid for Japanese F. rotunda.	en	Pfingstl, Tobias, Hiruta, Shimpei F., Hagino, Wataru, Shimano, Satoshi (2021): Juvenile morphology of seven intertidal mite species (Acari, Oribatida, Ameronothroidea) from the East Asian region.

4F7B1E5DFFA4FFE4FF74290FFF6CB77F.taxon	discussion	Remarks Adults of A. reticulatus are characterized by the name giving reticulate cuticular notogastral pattern, whereas this pattern is best observed around the medial notogastral setae (e. g. Luxton 1992, own observation). The reticulation results from slightly elevated cuticular lines that are connected at various points. Juveniles also show a distinct reticulate pattern on their centrodorsal plate, but the pattern is clearly visible all over this plate (except for the inverted Y on the posterior half) and it results from irregular scalelike elevations (a negative shape from the structure shown in the adults, so to speak). Juveniles of Alismobates pseudoreticulatus show the exact same pattern (Pfingstl 2015) but the adults of this species possess only remnants of the reticulate pattern framing the bases of centrodorsal notogastral setae. So, adults can be distinguished based on this trait, while juveniles cannot be. Moreover, we could not find any difference between juveniles of both species that makes an identification on species level impossible.	en	Pfingstl, Tobias, Hiruta, Shimpei F., Hagino, Wataru, Shimano, Satoshi (2021): Juvenile morphology of seven intertidal mite species (Acari, Oribatida, Ameronothroidea) from the East Asian region.

4F7B1E5DFFA4FFE5FC3E28D2FD75B79F.taxon	discussion	Remarks When Luxton (1992) erected the genus Arotrobates, he provided sketchy drawings of the legs of A. lanceolatus and mentioned at least in the key that members of this genus show conspicuous crests on all femora. Apart from this info, he provided very few further details on leg features whereas he mostly reported appearances of solenidia, for both known species. Later, Karasawa and Aoki (2005) redescribed A. granulatus from the southern and central Ryukyus and also gave only vague information on the legs, e. g. they provided length of each segment and wrote a sentence about pigmentation, but in contrast to Luxton (1992) they did not mention ventral carinae on femora at all. The latter trait, however, is present in the Japanese specimens and represents a prominent feature that is already developed in the juvenile stages. The setation and solenidia, presented herein for the first time in detail, are only based on Japanese A. granulatus material. No porous areas could be detected on any leg segment in any stage. Another characteristic trait of Arotrobates are the plough-like ventral epimeral carinae and although this feature is not developed in any juvenile stage, the epimeral integument of the nymphs appears to be more folded and less tight than in any other selenoribatid juvenile. This extension of integumental surface could already be an indication of the later developing ventral epimeral carinae.	en	Pfingstl, Tobias, Hiruta, Shimpei F., Hagino, Wataru, Shimano, Satoshi (2021): Juvenile morphology of seven intertidal mite species (Acari, Oribatida, Ameronothroidea) from the East Asian region.

The only found differences between I. taiyo and I. tyida juveniles concern the development of tibial setae, i. e. the antiaxial lateral setae on tibia I and III appear already in the deutonymphal stage in I. tyida but they appear later (possibly in tritonymph but due to lacking data not confirmed yet) in I. taiyo.	en	Pfingstl, Tobias, Hiruta, Shimpei F., Hagino, Wataru, Shimano, Satoshi (2021): Juvenile morphology of seven intertidal mite species (Acari, Oribatida, Ameronothroidea) from the East Asian region.
